Failures

The following failing examples will throw an exception with a message explaining why the assertion failed.

await Page.SetContentAsync(@"
<html>
  <body>
   <div id='foo'>Foo</div>
  <body>
</html>");

var div = await Page.QuerySelectorAsync("#foo");
await div.ShouldHaveContentAsync("Bar");

Expected element to have content "Bar", but it did not.

await Page.SetContentAsync(@"
<html>
  <body>
   <form>
    <input id='foo' value='Foo' />
   </form>
  <body>
</html>");

var input = await Page.QuerySelectorAsync("#foo");
await input.ShouldHaveValueAsync("Bar", "that would be the perfect example");

Expected element to have value "Bar" because that would be the perfect example, but found "Foo".

Samples

Sample projects are located in the samples folder.

This is an example with NUnit:

using System.Threading.Tasks;
using NUnit.Framework;
using PuppeteerSharp.Contrib.Should;

namespace PuppeteerSharp.Contrib.Sample
{
    public class ShouldTests
    {
        IBrowser Browser { get; set; }
